TECHNICAL FIELD

The present disclosure relates to a refrigerator. More particularly, the present disclosure relates to a refrigerator capable of preventing deformation due to sagging of a sliding shelf even if items with large size and weight are placed on the sliding shelf, and smoothly achieving a sliding operation of the sliding shelf.

BACKGROUND

In general, a refrigerator is a home appliance for storing food in a refrigerated or frozen state in a storage compartment opened and closed by a door. The refrigerator may generally include a refrigerator compartment for storing food in a refrigerated state at a low temperature and a freezer compartment for freezing and storing food in a frozen state.

Refrigerators that have been recently released have a tendency to provide a refrigerator compartment, that is used relatively more frequently than a freezer compartment, at an upper portion of a main body and to provide the freezer compartment, that is used relatively less than the refrigerator compartment, at a lower portion of the main body. In particular, a French door refrigerators, in which a refrigerator compartment is opened and closed by two pivot doors that are respectively hinged and coupled to the left and right sides of a main body and are arranged side by side from left to right, and a freezer compartment is opened and closed by a drawer door slidably installed, have been recently in the spotlight.

Such a refrigerator may have a vegetable compartment to separately store vegetables or fruits that must be kept fresh. In the refrigerator, a plurality of shelves may be installed in a storage compartment so as to partition the storage compartment in an up-down direction, and hence various types of foods, food materials, etc. can be stored in partitioned spaces.

Among the plurality of shelves installed in the storage compartment, a shelf positioned directly above the vegetable compartment may be slidably installed so as to be pulled out forward. A shelf positioned on the slidable shelf may be detachably installed, and thus may be detached when the storage compartment needs to be widely used.

With regard to the refrigerator, a related art refrigerator is disclosed in Korean Patent No. 10-1995427.

The related art refrigerator includes a main body having a storage compartment, a drawer that is installed in the storage compartment, has an upper opening, and is provided to be pulled out, a shelf mounted to be pulled out while selectively closing at least a portion of the upper opening of the drawer, and a cover that is disposed to overlap the shelf, is mounted to cover the upper opening of the drawer, and covers and closes the drawer even when the shelf is pulled out. A handle that can be gripped to selectively pull out the shelf is provided at a front portion of the shelf. The shelf includes a fall prevention portion that is provided at an upper surface of a read end and prevents storage items, that has been positioned on the shelf when the shelf is pulled out, from falling behind the shelf. A portion of the cover is formed of a transparent or translucent material so that items stored in the drawer under the shelf are visible.

However, the related art refrigerator has a problem in that the shelf (particularly, a center portion of the shelf) is deformed since the pull-out shelf sags downward when items with large size and weight are placed and stored in the pull-out shelf.

Further, the related art refrigerator has a problem in that an obstacle occurs in a sliding operation of the pull-out shelf when items with large size and weight are placed and stored in the pull-out shelf.

Further, the related art refrigerator has a problem in that the disassembly and assembly of the cover are poor since the cover is mounted over the entire left-right width of the main body to cover upper portions of several drawers.

Further, the related art refrigerator has a problem in that it is difficult to disassembly and assembly the pull-out shelf.
